3. Diesel Fuel Auto-Ignites

A big advantage of driving a car or truck powered by a diesel engine is that diesel fuel automatically ignites to power the engine. This advantage provides a big benefit since by not requiring spark plugs or wires, the overall maintenance costs of the automobile are significantly lowered as compared to gasoline powered cars and trucks. Even though a diesel engine uses a four-stroke combustion cycle like a gasoline engine (intake, compression, combustion, and exhaust), it directly injects the fuel to the combustion chamber. The heat of the compressed air then ignites the fuel delivering the big benefit of not requiring spark plugs to ignite the fuel to keep the engine running. This advantage allows the engine to rely on fewer components to continue operations delivering a big advantage to consumers.
